Abstract

L'invention concerne une feuille d'amortissement à adhérence magnétique possédant des propriétés d'amortissement améliorées et d'une faible teneur en ferrite ainsi que le procédé pour sa préparation. La masse magnétique (1) est dans ce cas introduite dans des bandes sur un côté de la surface de la couche de la masse d'amortissement (2). La totalité de la masse magnétique est magnétisée, contrairement à la feuille connue à deux couches.The invention relates to a magnetic adhesion damping sheet with improved damping properties and a low ferrite content and the process for its preparation. The magnetic mass (1) is in this case introduced in strips on one side of the surface of the layer of the damping mass (2). The entire magnetic mass is magnetized, unlike the known two-layer sheet.
